LNHU130608R-L55T WKK25G milling insert for cast iron | Walter Tools

The LNHU130608R-L55T WKK25G is a rectangular milling indexable insert designed for productive machining of cast iron, featuring Tiger‑tec Gold coating and a chipbreaker tuned for short, breaking chips.

• Tiger‑tec Gold coating for wear resistance
• Optimised for cast iron machining
• Rectangular insert, 13 mm width
• 0° negative rake, 0.8 mm corner radius

Higher productivity through engineered coating and grade

The coated carbide grade WKK25G, part of the Tiger‑tec Gold family, is formulated for the abrasive wear typical of cast iron machining. This creates a direct productivity advantage: longer cutting edge life and fewer insert changes reduce downtime and machine idle time. The coating technology improves thermal stability and adhesion, which means more consistent performance under the shock‑prone conditions often encountered when milling grey and nodular cast iron. As a result, the insert delivers reliable tool life and predictable replacement intervals, supporting efficient production planning.

Geometry and chip control for safer, cleaner milling

The rectangular geometry with a 13 mm cutting width and the L55T chipbreaker are designed to handle the short, brittle chips produced by cast iron. The combination of a 0° negative rake and a 0.8 mm corner radius gives a robust cutting edge that resists chipping during interrupted cuts and heavy radial engagement. Improved chip control reduces recutting and potential damage to the workpiece, helping to maintain surface quality and decrease rework. These design features translate into fewer tool interventions and steadier cycle times on milling operations.

Practical application guidance and process benefits

This insert suits face and peripheral milling operations where consistent chip formation and wear resistance are priorities. The grade is optimised for cast iron according to ISO group K, offering a balance between wear resistance and toughness for typical foundry alloys. The dimensional and tolerance data support straightforward seat fitting and repeatable clamping. For tailored parameter settings or specific workpiece conditions, technical consultation is recommended; Metav Werkzeuge can provide application hints and availability information to match machining goals while safeguarding component finish and tool economy.

FAQ

What materials is this insert intended for?
The insert is intended primarily for cast iron machining; the WKK25G grade and Tiger‑tec Gold coating are optimised for the abrasive, short‑chip behaviour of cast iron.

How does the L55T chipbreaker help process stability?
The L55T chipbreaker promotes the formation of short, controllable chips when milling cast iron, which reduces recutting and improves surface consistency when using the LNHU130608R-L55T WKK25G insert.

Is the insert suitable for interrupted cuts and heavy engagement?
Yes. The 0° negative rake and the 0.8 mm corner radius provide a robust cutting edge that withstands shock and reduces the risk of chipping during interrupted cuts.

Which series and coating does the insert use?
The insert belongs to the Tiger‑tec Gold series and uses a coated carbide grade WKK25G, promoting wear resistance in abrasive applications.

How should the insert be specified when ordering?
Specify the full designation (LNHU130608R-L55T WKK25G) and mention Walter Tools as the manufacturer; the SKU is LNHU130608R-L55T-WKK25G-WALTER for unambiguous identification.
